Types of facial rollers？

Jade is one of the more common stones you’ll find in rollers. It’s been used for centuries.

You'll  also find face rollers made of:

rose quartz
amethyst
obsidian
metal
Jade and metal are naturally cold materials and will not need to be stored in the refrigerator to give a cooling sensation to the skin.

Rose quartz can hold its temperature (hot or cold) for a long period of time. So if you want a colder roll and are planning to use it for more than a minute or two, quartz that’s been cooled in the fridge is your best option.

Jade is a softer stone than rose quartz, so a quartz roller may last longer and not break as easily if dropped.

However, jade may not be as smooth as some of the other stones, but this added friction may be especially helpful for contouring.

Traditionally, amethyst is said to help purify the skin, and it may help to treat acne. However, research is needed to support this claim.
